Project Scale Model
Main Content Standards
Measurement and Geometry2.0 Students compute the perimeter,
area, and volume of common geometric objects and use the results to find measures of less common objects. They know how perimeter, area, and volume are affected by changes of scale
Mathematical Reasoning2.0 Students use strategies, skills, and
concepts in finding solutions
Objectives
Know and be able to apply
necessary formulas to find surface
area and volume
Use scale factors to find new surface
areas and volumes
Use understanding of scale factors and apply it to
real-world situations
Assess the reasonableness of the solutions
to real-life situations
Identify steps & patterns used
to answer problems and apply them to newer, more
complex problems
Independently break down a
complex problem and
correctly progress
through the steps to solve it.
GoalsStudents
• Confidently & accurately calculate Surface Area and Volume for all 3-D solids.
• Understand pattern behind scales and unit conversions with respect to Surface Area and Volume.
Personal• Thoroughly gauge
students needs and address them accordingly.
Gauging Student Needs Assessment
Think-Pair-Share Review past lessons that
pertain to Surface Area Volume (Area & Perimeter)
Go over work with one other student; help each other correct and quiz one another
K-W-L Self-report from students about what they
know and don’t know Students have a say in the direction of
their learning
Think-Pair-Share
Essential Question
Question Purpose
How can using math improve
our lives?
1. To get students to think about where they use math in their life.
2. To get students to consider what life would be like if they never used math.
Unit Questions
Why would we find Surface Area in the real
world?
Why would we find Volume in the real world?
Content Questions
What does Surface Area mean, and what does Volume
mean?What are the different formulas for Surface Area and Volume?
What are the unit measurements for Surface Area and Volume?
What is a scale factor?What is the pattern of change in Surface Area and Volume when a
scale factor is used?
Project
To make the connection between classroom and real world and make applications.
To encourage students to develop essential 21st Century skills.
To build confidence in students.
Project Summary
Assignment SkeletonWith a partner, find a 3-D solid object at home that you can replicate on a larger or smaller scale. Record its measurements, surface area, and volume.
• Students will convert measurements, surface area, and volume from cm to meters and kilometers.
• Students will use given scales to find the measurements, surface area, and volume of a solid that would be similar to theirs.
• Students will produce a scale model of their 3-D object.
